Summarized briefly is the research conducted at the University of Texas on the concerns of teachers. Two branches of research have been pursued. The distinction lies in the type of assessment used. The first, the Teacher Concerns Statement (TCS), an open-ended free-response instrument, asks the question: "When you think about your teaching, what are you concerned about?" The second instrument, the Teacher Concerns Checklist (TCCL), asks the same question as the TCS and is followed by a list of 56 items. The subject responds by placing a check under one of five categories representing the degree of concern felt. Studies of the TCS and TCCL have led to the conclusion that teachers are most concerned about: self-survival, teaching, impact on pupils, and about the teaching situation. The TCCL promises to be a viable research instrument, largely because of its improvement over the earlier TCS in terms of reliability and increased ease in scoring. (RC)
